Joaquin Phoenix moody on Letterman

Joaquin Phoenix slurred his words and seemed to be confused during an appearance on David Letterman yesterday. The actor refused to make eye contact with the jovial host and hid beneath some dark glasses and overgrown beard. The actor told Letterman he was "doing fine" after the host stumbled over the introduction of a clip about his new movie, Two Lovers. Letterman snapped back: "Thanks. High praise coming from you." When the audience laughed at Letterman's gibes, the actor hit back, saying: "What do you have them on? What do you gas them up with?" Some insiders have suggested that Joaquin's moody routine was merely a stunt for a spoof documentary about an aspiring hip hop artist. SOURCE: TELEGRAPHSee other celebrity tirades
